ATLPARATU$ FOR MAKING EGG-SIEIAIIES.

teale511.

To all whom it may concern:

Be it known that I, ASHTON D. Ross, a citizen of the United'States, residing at Fitchburg, county of Worcester, and State of Massachusetts, have invented an Improvement in Apparatus for Making Egg-Shakes, of which the following description, in oonneetion with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to an apparatus for making so-qalled egg shakes, and has :lor its object to provide a novel apparatus adapted to rapidly and thoroughly mix the egg, milk, and other ingredients, in such a way that the e g will be thoroughly broken up and comp etely mixed with the other ingredients, and to provide a construction wherein the cup or other receptacle is given a movement of the same character as that given to the cup by an operator when he makes the egg shake by hand; and further-lo provide a machine for this purpose which is com pa ratively simple and inexpensive to manutaeture and can he easily operated.

Referring to the drawings wherein l' have shown one ernbodin'ient o'l? my invention, Figure 1 is a side view of an apparatus made in accordance with the invention; Fig. 2 is a top plan view; Fig. 3 is a view of the cushion spring; Fig. 4 is a view showing the clamp for clamping the cover on the cup; Fig. 5 is a section on the line e--m, Fig. 1.

1 designates the cup or other receptacle oi usual form in which the ingredients are -mixed, and 2 the cover for the cup. At

most soda fountains the egg, milk and other ingredients are placed in the cup 1. and the cover 2 is applied thereto and then the attendant at the soda fountain gives the cup a violent shaking in his hands to mix the ingredients. As stated above my apparatus is adapted to produce substantially the some shaking motion of the cup 1 as that which is given by the operator. lhe cup 1 is adapted to be sustained in a suitable holder 3 which is sustained on a flexible or resilient arm -1l that in turn is mounted on a rook-shall 5 journaled in hearingsjn a suitable frame t3. Said frame is preferalily constructed so that it can be readily securled to a table, counter, or other surface, and it) is shown-as provided with the feet portion {7 to rest on the talile and through which sclrews 8 or other fastoning means may be inserted, and a vertielal Specification of Letters Iatent.

web 5') adapted to support the operating parts as will be presently described.

The cover is held in position by means of a clamping member 10 which is shown as pivotally sustained on the bail 11, the arms 12 of which are shown as provided with the loops '1 3 which furnish a certain amount of give or resiliency to the hail. This bail can conveniently be made of wire bent into the proper shape. The ends of the arm 12 oi the bail are pivotally mounted in a locking member 14 which is pivoted to the holder 3, as at 15, the point .16 where the arms engage the locking member being eccentric to the points 15. .\'l.ter the cover .2 is applied to the cup 1. the bail ll is swung into operative position will) the clamp 10 engaging the top of the cover and then the locking member ll is swung downwardly into the lull line position l ig. -l' thereby lirmly clamping the cover to the cup. When the locking member occupies said full line position the points l where the bail ll is connected thereto pass by the pivotal point 15 oli the bail so that when the locking member fl-l strikes the cap the device is securely locked. in place. When lhe locking member 'llis lifted, however, the cover is unclamped and can be readily rcu'ioved.

Suitable means are provided for oscillating the rock-shaltoltljereby to give the cup '1. a violent shaking and because of the resiliency oi" the arm 4 the movement which the cup will have is very similar to that which is given by hand. While it is pos sible to operate the rorkshul't 5 in various ways without departing 'lfrom my invention l prelor the construction herein illustrated, as it has been found to be one which can be easily operated. noclrd to a member 17 which is last on the rock shaft 5 and which is provided with an arm 15% that is connected by a link it) with a crank disk 30 mounted on a stud shall ll. 'lhis crank disk has rigid lhormvilh a pinion 3'2 which meshes with and is driven by a driving gear Elfil uullltd on a shalt ll that is journ'illcd in the l'ruuu said shall having a crank handle 35 last thereto by which it may be turned. mont ol my invention the shaft =lis sustained partly in bearings l'ormed in the web 9 and partly in bearings .26 carried by the spider 37, the gear 2? being confined botwecn the spider and the web .l. Any other The arm -1 is shown as coni I); the illustrated embodi" 'way' of securing the driving gear to the frame might be employed, however, without departing from my invention. By turning the crank handle 25 the crank disk 20 will be rapidly rotated, thus oscillating the member 17 and giving to the cup 1 the required oscillatory or shaking movement.

The rock shaft 5 is shown as having fastthereto an arm 28 provided with an adjustable counterweight 29, which counterweight acts as a balance for the weight of the cup 1 and its contents.

In order to make the operation of the device easy and smooth notwithstanding the shaking movement of the cup 1 and its contents I have provided a combined cushioning and reversing device vwhich not only cushions the oscillating movement of the rock shaft 5, but also helps to reverse the direction of movement of the rock shaft at the end of each oscillation. As herein shown the rock shaft. 5 has fast therewith an arm 30, the lower end of which straddles a'rod 31 carried by the frame, said rod being herein shown as supported at one end in a boss 32 formed on the bearing 33 for the shaft'Ql and supported at theother end in a flange 34 formed on the frame.

35 and 36 are two springs which encircle the rod 31, said springs being situated either side of the arm 30. I will preferably interpose sliding collars 37 and 38 between the springs and the arm, although this is not essential. These springs are so positioned that when the cup-supporting arm 4 swings upwardly, the arm 30 will engage the collar 38 just before the cup reaches the upper limit of its movement so that during the last part of such movement the spring 36 will be compressed and thereby act to assist in bringing the cup to rest, and at the same'time assist in starting the parts in the reverse direction. Similarly when the cup approaches the lower limit of its movement the arm 30 will engage the collar 37 and thus compress the spring 35, which spring will not only assist in bringing the parts to rest, but will by virtue of its action assist in starting the parts in the opposite direction. I propose to make the spring 35 somewhat heavier than the spring 36 because a greater force is required to cushion and reverse the movement of the cup at the lower-limit of its motion than is required at the upper limit of its movement because of the fact that the action of gravity assists in the reversing movement at the top of the stroke, but acts against the reversing movement at the bottom of the stroke. By the use of these springs 35 and 36 I find that it is possible'to operate the machine very rapidly and with great ease for the force necessary to reverse the movement of the cup and its contents is secured largely by the action of the springs 35, 36. While the machine is in Having described my invention, What I claim as new and desire to secure by Letters Patent is 1.
